    How the conversion runs. The encoding happens in your browser through FFmpeg.wasm. The file never leaves your device; nothing is uploaded to a server. Pick the output format from the dropdown above the file picker, drop the source, and the page returns a downloadable result when the encode finishes.

    Container repack vs re-encode. Switching between MP4, WebM, MOV, AVI, and MKV repackages the existing streams without re-encoding, so the original video bitrate, frame rate, and resolution are preserved exactly. Switching to an audio format (MP3, AAC, OGG, FLAC, M4A, WAV) extracts the audio track and re-encodes it. Pick the MP3 bitrate from the selector above: 128 kbps for a small file, 192 kbps default, 256 or 320 kbps for higher quality. FLAC and WAV are lossless and ignore the bitrate setting.

    In-Browser HD Video Converter

    Convert HD video files to MP4, WebM, MOV, AVI, or MKV, or pull the audio track to MP3, AAC, OGG, FLAC, M4A, or WAV, all right in your browser. Files stay on your device; the converter runs locally via FFmpeg.wasm with no upload, no install, and no account. For the original FFmpeg online tool on this site, see video-converter.html.

    Use this when you would rather not upload a clip to a server, when the network is slow, or when the source contains anything you want to keep local. The dropdown above the file picker lists the output formats; pick one before dropping the file.

    Compress video online free

    Move an HD clip between MP4, WebM, MOV, AVI, and MKV containers right in the browser without re-encoding - the source bitrate, frame rate, and resolution are preserved exactly while the container swap repackages the streams into the requested wrapper. Picking a more efficient container that the recipient supports often shaves the file size on disk because modern containers like WebM and MP4 carry less per-frame metadata overhead than older wrappers; the repack runs locally on the device, so the source file never leaves the laptop or phone.
